About Imodium Syrup SF
  1. What is Imodium?

    Imodium is the brand name for Loperamide, which is a medication used to relieve diarrhoea. Available as a syrup, tablet or capsules, Imodium is one of the most used diarrhoea relief remedies.

    You can buy Imodium tablets and capsules over the counter. The syrup version of this medicine is only available on prescription.

    What is Imodium used to treat?

    Imodium (Loperamide) is primarily taken for diarrhoea relief, but it can also be used to treat short-term diarrhoea or irritable bowel syndrome (IBS).

    Additionally, you can use this product to aid in longer-term issues, such as bowel conditions like Crohn's disease.

    How does Imodium work?

    Imodium contains loperamide hydrochloride as the active ingredient. Loperamide is an anti-motility medicine that works by slowing down food as it passes through the gut.

    By slowing down how quickly the food moves through the digestive system, your body can take on more water from the intestines. This makes your stools firmer and reduces how often you need to go to the toilet.

    Whyis Imodium recommended for diarrhoea?

    Imodium is renowned for being able to provide fast-acting relief from diarrhoea symptoms, getting to work very quickly and giving long-lasting results.

    If taken in the morning, this medicine should provide all-day relief from your symptoms. The effects of Imodium Syrup SF last for between 8 and 12 hours.

    Who can use Imodium?

    This medicine is not suitable for you if:

    • You are constipated or your stomach looks swollen
    • You have severe diarrhoea after taking antibiotics
    • An inflammatory bowel condition flares up (such as ulcerative colitis)

    Please contact your doctor before you take Imodium if:

    • You are pregnant, trying to get pregnant or are breastfeeding
    • You have had an allergic reaction to loperamide or any other medicines in the past
    • You have had diarrhoea for more than 48 hours
    • You have AIDS and your stomach becomes swollen
    • You have blood in your stools and a temperature of more than 38C
    • You have liver problems
    • You aren't able to digest some sugars

    If you suffer from diarrhoea with IBS, please speak to your doctor before taking this product if:

    • You are aged 40 or over and it has been a while since your last IBS attack, or if your symptoms are different this time
    • You have nausea/vomiting
    • You have lost weight or lost your appetite
    • You have bad constipation

    • You have a fever

    This information may not be exhaustive. Always read the patient leaflet for full details on why Imodium may be unsuitable for you.

    Can you buy Imodium over the counter?

    Imodium tablets and capsules are available over the counter. The syrup must be prescribed by a doctor and cannot be bought in pharmacies or supermarkets.

    Can you buy Imodium online in the UK?

    You can buy Imodium online from Medicine Direct, but first you will need to fill out an online questionnaire to make sure it is suitable for you to take. Your answers will be reviewed by a prescriber before your order is approved.

    If you place your order by 2pm, we can also offer you next day delivery on your medication.

    Medicine Direct is fully regulated by the General Pharmaceutical Council, which means that we can guarantee all of the medication sold from our online pharmacy is genuine and approved for sale in the UK. Never buy any medicine online unless it is from a regulated pharmacy. 

    Imodium alternatives

    There are many medicines available which can effectively treat the symptoms of diarrhoea.

    Imodium is the branded and syrup version of Loperamide Hydrochloride tablets.

    Imodium tablets and capsules come in many different forms. These tablets can be bought over the counter from your local pharmacy or supermarket.

    Another treatment for diarrhoea is Norimode. While you will need a prescription to buy these tablets, Norimode can provide fast acting relief from diarrhoea. Norimode also contains loperamide hydrochloride, so works in the same way as Imodium Syrup SF.

    For an over the counter treatment that can be used by adults and children alike, Dioralyte may be the answer. Dioralyte comes as a powder that should be mixed with water to make a blackcurrant-flavoured drink. This medicine works to prevent you from becoming dehydrated when suffering with diarrhoea.

    All of these medicines, among others, can be ordered from Medicine Direct after you have completed an online questionnaire.
